IMPROVEMENT m CLOD-CRUSHERS.

Specification forming part of Letters-Patent No. 23,415, dated March 29,1859.

To all whom it may concern:

Be it known that I, E. B. WAY, of Jerseyville, in the county of Jerseyand State of Illinois, have invented a new and Improved Implement orDevice for Crushing Glods and Pulverizing the Soil; andI do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in whichw Figure 1 is a transverse section of myinvention, taken in the'l-ine a a, Fig. 2; Fig. 2, a longitudinalsection of same, taken in the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

To enable those skilled in the.art to fully understand and construct myinvention, I will proceed to describe it.

A represents a rectangular frame, to the front end of which a draftpole, B, is attached, and within this frame the cylinder of slats O isplaced, the axis of the cylinder being at right angles with thedraft-pole, and the cylinder allowed to turn freely within the frame.The frame A is constructed of wood and may be of any suitabledimensions. The axis or shaft a of the cylinder 0 is of wood, providedwith a journal, b, at each end, the journals being fitted in properbearings in the frame. The shaft is of polygonal form, and has a seriesof radial arms or spokes, c, fitted in it, one series being at thecenter and one near each end,as shown clearly in Fig. 2. The arms 0 maybe of cylindrical form, having tenons on their inner ends to fit inmortises in the shaft a. The outer ends of the arms may also have tenonsformed on them, said tenons being fitted in fellies d, which form rimsfor the arms. It will be seen that there are three rims, d d e, and byreferring to Fig. 2 it will be seen that the rims cl d, near the ends ofthe shaft, are not so deep as the center one, 0.

To the rims d d c slats f are attached. These slats are all parallelwith each other, and the'shaft a may be formed of any hard wood. Theslats are nearly equal in length to the shaft a, and they have obliquesides, g--that is to say, they are transversely of taper form, as shownclearly in Fig. 1. The slats are let into the rims d d c, the rimshaving their peripheries recessed, as shown at h, to receive the slats,which are also notched or recessed at the points where they fit into therims, as shown at 1", in order that the outer sides or treads of theslats will be flush with the peripheries of the rims. The slats and rimsare bound with iron hoops j, which may be shrunk on the cylinder andthen secured by bolts.

It has been previously mentioned that the central rim, e, is of greaterdepth than the outer ones, (1 cl. The object of this difference in thedepth of the rims is to permit the slats f to be increased in depthgradually from their ends to their centers, as shown clearly in Fig. 2,and thereby insure a requisite degree of strength and stiffness.

The slats f may be placed at any suitable distance apart, but sufficientspace should be allowed to enable the slats to act efficiently on theclods.

The operation will be readily seen. As the implement is drawn along, theslats f bear upon the clods and break or crush them, the broken piecesin a majority of cases passing within the cylinder between the slats andraised to some extent by its rotation, the raisin g of the crushed clodsbeing favored by the V-shaped recesses between the slats, said form ofrecess being due to the oblique sides of the slats. The crushed clods,when they reach a certain height, fall of course from the recesses andwithin the cylinder on the inner sides of the slats below, and the partsof the clod are again divided by the fall and pass out pulverized fromthe cylinder. If the ground be very dry, the slats f will crush theclods and pulverize them by their weight only, and the pulverized clodswill not adhere between the slats; but in case the ground be slightlymoist it will be sufficiently adhesive to lodge between the slats, aspreviously described. The implement therefore is efficient in eithercase.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- The employment ofthe oblique-sideddoubletapered slatsf, in combination with rims d d 0, so that the clodsthat wedge between the slats will be carried up and then dropped andbroken within the wheel, as herein shown and described.
